Angles of Parallel Lines - Algebra Applications

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They are always the same distance apart and have the same slope.

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of the transversal and outside the two lines.

Front

What is the relationship between corresponding angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, corresponding angles are equal.

Front

What is the relationship between alternate interior angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, alternate interior angles are equal.

Front

What is the relationship between alternate exterior angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, alternate exterior angles are equal.

Front

If two angles are supplementary and one is 70 degrees, what is the measure of the other angle?

Back

The other angle is 110 degrees, since 180 - 70 = 110.

Front

If angle 1 is 44 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle is also 44 degrees.
